DEVICE FOR DAMPENING ENERGY OF SUPERSONIC LIQUID STREAM Russian patent published in 1998 - IPC

FIELD: metal-working equipment. SUBSTANCE: this relates to systems for cutting by supersonic stream of liquid. Device is made in the form of body with its space connected with pipe union for receiving supersonic stream of liquid. Pipe union is located coaxially with outlet pipe union, and their ends create circular slot. Made in body is vacuum space for drawing in part of sprayed working liquid. Vacuum is created at passing supersonic stream of liquid through circular slot made between receiving and intermediate pipe unions. Device ensures automatic removal of working liquid splashes created due to loss of energy by peripheral zone of stream after its appearing from cutting zone. EFFECT: high efficiency. 2 dwg
